Question

The order of three layers of cells in retina of human eye from inside to outside is

• A. Bipolar cells, photoreceptors, ganglion cells
• B. Ganglion cells, rods, cones
• C. Ganglion cells, bipolar cells, photoreceptor cells
• D. Photoreceptor cells, ganglion cells, bipolar cells
• E. Ganglion cells, photoreceptor cells, bipolar cells

Answer 1

Answer: (C)

Ganglion cells, bipolar cells, photoreceptor cells

Retina of eye ha three layer of cells:

Ganglion cells: These are in the outer layer and form the optic nerve that carries visual information to the brain. These cells take information from bipolar cells.

Bipolar cells: These cells are present next to ganglion cells and take information from photoreceptor cells.

Photoreceptor cells: These are present next to bipolar cells and detect the daylight vison and low light vision. There are two types of photoreceptor cells in retina, cones (detect daylight vision and coloured vision) and rods (detect low light vision).

So, the correct answer is 'Ganglion cells, bipolar cells, photoreceptor cells'.
